The Arizona Department of Transportation has initiated a study along a section of Loop 303 in the Northwest Valley to address how future growth in the region would impact the highway. The study will examine the benefits of adding a third general purpose lane in each direction between Happy Valley and Lake Pleasant parkways; constructing a new traffic interchange to tie in with the city of Peoria’s future extension of Jomax Road; and building a new bridge over the Beardsley Canal.

What to Expect:

During the construction phase, shoulder closures along the Loop 303 are anticipated and temporary single-lane closures might be necessary. ADOT would maintain at least one lane of travel in each direction while work is underway.

Schedule:

The study is scheduled to last 12 months.

Construction is scheduled to begin in fall 2020. Information about the duration of construction will be provided when a project schedule is confirmed.
